PCT No. PCT/GB80/00168 Sec. 371 Date Jun. 15, 1981 Sec. 102(e) Date Jun. 15, 1981 PCT Filed Oct. 16, 1980 PCT Pub. No. WO81/01174 PCT Pub. Date Apr. 30, 1981.Wave energy apparatus comprises a hollow buoy (2) for floating in water. The buoy has a turbine (5) which rotates in response to air flow into and out of the buoy (2) through a nozzle (4). The turbine (5) is designed to rotate in the same direction regardless of the axial direction of air flow. The air flow is caused by the change of level of water (W) within the buoy in response to wave motion. To enable rocking motion to be accommodated as well as vertical motion, the interior of the buoy is divided into a plurality of conduits (9), by means of partitions (6), the conduits directing air to different portions of the turbine (5). The conduits (9) preferably have lateral openings (10) and may be defined in part by upwardly inclined portions (11) of an inertial body (8). In an alternative embodiment the buoy has a closed bottom and liquid in the buoy is acted on by a centrally disposed air spring. |
